<p>Hello list,</p>
I seem to be hitting a strange problem trying to use a sysmoQMOD
with Ofono and a Telit Modem (HE910)<br>
There seems to be a window of around 30 seconds after starting
osmo-remsim-client-st2 whereby ofono cannot talk to the modem. <br>
There is no response to any AT commands on either the Modem or the
Aux port.<br>
After about 30 to 40 secs AT commands start working again and I can
enable the modem.<br>
It seems that switching from physical SIM to remote SIM causes the
modem to lock-up for a while.<br>
Anyone else seeing a similar issue?<br>
<p>I've upgraded the firmware to the latest (0.5.1.24-bb9b0) but it
make no difference.</p>
<p>Regards</p>
<p>Alan<br>

<p>Here is a debug log of the firmware with my notes:</p>
